-M invention relates to apparatus for charges of molten glass and par- -ticular y to a glass feeder of the type in which the glass is discharged through an the bottom of a container, thebd' gulated and controlled as re ating plungeral ie'thc outlet;

arge being're rejecting into the glass n feedcrs'of this type, is commonly provided in the floor ofa furnace boot-or extension, :1, jacent the-forward end .of the boot. The regulating plun er is in-the main yof the glass in the boot;

It which gives a comparatively poor control over the shape and size lof the issuing charges. of lass. A further ob'ectionable feature is t at thecurrent of e issuing glass is in a. direct line from the furnace to.

ning, so that there is 0. ate ation and illing of the glass on" the side of the-opening farthest from the. furnace. As a result, the issuing columnofglass is unsymmetrical and not of produces defects in the finished ware.

An object-of the present invention is to provide means ior separating from the main supply, a comparatively small mass of the glass over the outlet so that the expelling and retarding client of the reciprocating plunger or' regulator is groan-rand under tter control than when working in a comparatively large glass. 1 A. fnrther object of the invention is to )llflltle suitable means for causing the glass Issuing from the outlet to be drawn from the supply at a point beneath the surface thcreo whereby a better quality of glass is mass of further obicct of the invention is to provide a practical construction in which the issuing mass or column of glass is symmetrical and of uniform tel'npcraturc on all i 1 Other objects of the invention will appear hereinafter.

There is disclosed herein subject matter also disclosed in my co-pending applications, Serial Number 385,591, means 'for forming charges of molten glass, and Serial meansof a periodically reciprocatedreciprocated directly wvhirh projects vertically flow through the outlet, an

A furnacehoot or extension 10 1s continuo'usl supplied-with molten 'glass 11 from the urnacel2. The glass issues periodically through an outlet 0 the boot. The-disc lated hy a clay plunger or regulaton glass and is periodically reciprocated tically. The upward movementof. the plunger opt-rates to retard or reverse the 'd its downward movmucnt exerts an expelling action on the glass. 1 i

The 0 )ening 13, as shown. is fornual in a clay bus ring 15 above which isan opening or well 16 in the floor of the boot.

Surrounding the regulator 14 is u'housing 17 consisting of awsuhstantially cylimlrival wall formed "of refractory materiah -'l"ho. internal dianu-ter ofthis wall is substantially greater than the diameter oflhc regulator to provide a chamber of sufliciunt' capacity to hold enough glass to form one or more charges. The lower end of the wall 17 is tapered downwardly and inwardly and projocts within the well 16. The wall 17 is extended upward through-the cover 21 of the boot. and is ol':'l'rduced diameter at its u pnportion. The wall is cut away at 18 to arm a substantially V-shapcd recess, as shown in Figure 4, providing a passageway at the front of theregulator through which the glass may freely enter the housing 17. At the rear of the regulator a comparatively uresfi is a sectional side elevation of a' downward into the verapparatus 4 is a fra mentary elevation view;

the housing shown in through the regulacning 13 in the floor of uirge'of glass is reguloo *s'tantially uniform tempe narrow space 19 is provided which permits a restricted flow of glass between the housing 17 and the walls of the well 16, so that these parts will not freeze'together. The greater portion a of the lass, however, is caused to flow around the ousmg 17 and in to the later at the front of the later. In tlns manner, the glass is maintained at subof the regulator and clnllil and stagnation of the glass at the front oi the boot is prevented. It will be seen that with this orrangement, the glass issui from the outlet 13 is drawn from the su 1p y at a" int beueath the surface therco which g as is'fof better quality and at a higher and more uniform temperature than the surface An opening Kl may be provided througi the wall of the housing at a point above the glass level. This olpening permits the hot gases to enter said musing and maintain a high tcmpcratlnc above the glass within the housing. The regulator '14 is also therebv protected against extreme and sudden variations of temperature which. cause frequent cracking and break of such regulators.

The par-til! is a d i stable vertical] by means of a hand wheel $1 on a vertica rod having a screw threaded mounting in 'a stationary bearing sleeve 25, the upper end of said rod being rotatively connected to an arm 26 carrying the housing 17. By adjustment of the part 17 11 opening 18 may bemoreor restrictcdto ne ulate the flow of glass heret trough. 'l e housing 17 is also rotativcly a stable. For this purpose the arm'26 is mounted on i a sleeve 28 fixed to the housing, and rotatable in said arm. A set screw 29 holds the honsing in adjusted position. I I Fifnres '5 and .6 show a lnwlification of tie I ousmg. 17. In this con=;rnction'qthe recess-18 is omitted, the lower end of said housingextending downward to the same level on all sides'of the regulator. There is thus provi ed an annular passageway l9 between the 'walls of the well Hi and the lower end of the housing. which passageway is of equal width at all sides of the icgnlator; An 0 inning .57 is provided in the wall I? below tnlc'rcl -of unlass in the boot and preferably near the surface of theglass. This opening-is at the front side of the rogulator l4. 'ith this arrangement of the opening 27, the glans which is expelled through the outlet [3. or the major portion of such glass. is caused to How forward to the front end of the boot and enter said 0 wuing 27. sin that stagnation and freezing o the glass at the front of the boot is prevented.

In operation, the regulator 14 is periodically reciprocated vertically. As the regulabor rises, the glass enters the chamber 1'. thron h the opening 18 (Fig. 2) or the opening 2 (Fig. 5), the inflow of glass being rature onlall sides.

It will be noted that the regulator acts on a comwtivelv small volume of glass, the main y of gas being separated therefrom by the wall 17, 'so that the expelling and retardiig actionsof the regulator are more ronoun and under-better control than wit 1 the usual arrangement in which'sn'ch wall is-omltted, There is a seepage or restricted flowot glass through the-passage 19 (or 19') and under some conditions this passage may be enlarged so that a considerable portion of the ass flows therthrough. Modifications may he resorted to within the spirit and scope of my invention,-
